Nanguang has a long history of manufacturing static penetration probe. Its main technicians put into the manufacture of resistance strain sensor (probe) in the early 1990s. They have many years of practical experience and pioneering ability. The company manufactures complete environmental facilities in Anjiang. It has a production room of sensors with dust-free constant temperature and humidity. It also has a fatigue shaking table, a hydraulic test stand, an electronic universal testing machine and other confidentiality testing instruments. The company has a probe production license issued by the Ministry of Quality and Technical Supervision of the State.

At present, the static probes produced by Nanguang Company include conventional static sounding 10 cm 2, 15 cm 7 single and double bridge probes, multi-functional pore pressure static sounding probes, compression wave velocity static sounding probes, resistivity static sounding probes, special small diameter 5 cm? Static sounding probes and 15 CMR static sounding probes which can measure 12 tons (80 MPa) and large tonnage static sounding probes. They also cooperate with universities and scientific research institutes to develop high-sensitivity probes for marine soft soil and high-precision probes for high-speed railway. And cable-less probe, etc.

The probes manufactured by Nanguang Company are in line with the relevant national standards for static penetration technology. The quality and performance of the probes are constantly improving through the inspection and monitoring organized by the relevant state departments. They are the current domestic static penetration probes.
